Question

Not all enzymes work inside cells in the body. _________ enzymes are produced by specialized cells in the pancreas and digestive tract. From there, the enzymes pass out of the cells, into the _________ and small intestine where they come into contact with food molecules. Here, they catalyze the ________ of large molecules, which are then more easily absorbed by the body.

a) Intracellular, Bloodstream, Hydrolysis.
b) Extracellular, Bloodstream, Synthesis.
c) Intracellular, Stomach, Hydrolysis.
d) Extracellular, Stomach, Synthesis.

Answer 1

Extracellular enzymes are produced in specialized cells in the pancreas and digestive tract and act outside of the cells. They catalyze the hydrolysis of large molecules in the bloodstream and small intestine. Therefore, the correct option is B.

Step-by-step explanation:

Extracellular enzymes are produced by specialized cells in the pancreas and digestive tract. From there, the enzymes pass out of the cells, into the bloodstream and small intestine where they come into contact with food molecules. Here, they catalyze the hydrolysis of large molecules, which are then more easily absorbed by the body.The pancreas produces a bicarbonate-rich pancreatic juice that delivers these enzymes to the small intestine, aiding in this process. In the small intestine, most of the chemical digestion and absorption takes place, facilitated by the pancreatic enzymes and additional enzymes synthesized by the mucosal cells lining the small intestine.
